How to connect MS-access database using C#.Net.??

I'm using code as follow:

<add name="localhost" connectionString="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=data\guestbook.mdb;Jet OLEDB:Database Password=data123;"/>

But I'm getting Error msg as follow:

"System.Security.SecurityException: Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

Anyways without seeing the entire stack trace I can say that it's a system security exception. Are you sure that your application have enough credentials to access the db?
